nevermind I got it to work. It was as Matthias said, you need to figure out with the multimeter a bit wich cable is part of the throttle. I actually piggybagged on 3 wires coming out of the throttle and measured resistance to the cable down there.

so I have this scoot working now, pretty rudimentary just the bare minimum connected. I feel that this controller (same as Matthias) is total piece of chink shit ... works moderately good and he, 11 euro's shipped. I did add the extra copper traces and potted the caps a bit.
Top speed is about 30 km/h but I feel like the torque could be better. so next time I will invest in a better controller.

this is how it is now. As these bikes are street illegal in my country I use it to drive around the terrain I live, hence the basket strapped on the back to put tools and other crap in. I also do the odd drive around the neighbourhood.
The controller placement is not the most beautiful for now but it's not in the way. I will put a watertight box around it probably one day. I drilled an extra hole just down there cause the 3 phase and plus and minus where to short to comfortably connect.
I also wired in a switch to turn it on and off.

Hello!
I ordered this controller and it works just fine.
RON 69.19 30%OFF | 24V/48V 250W/350W Brushless Controller Motor Regulator Speed for Electric Bicycle E-bike Scooter E-ABS Sensor/sensorless
https://s.click.aliexpress.com/e/2BN7UNLK
Throttle works, e-abs works.
My question is does anybody know how many volts needs the lights below scooter to work?
Thank you!
No idea how much volts they need but if you have the polarity right just start with 5 volts, go up and see what works, it should not be too bright as it will damage the led.

Do you have any wirings picture or schematic? And how did you removed the controller? I can't remove it because there's too many cables on the controller location!

I will post a detailed photo of my setup later, but it's not very hard to figure if you know what you're doing. Just the throttle gave me a little headache.

The controller can be removed via the hole in the bottom of the scooter, it went in that way so should be able to come out just pull the wires out as well.

Hello,

I have 2 of these scooters, I have started replacing the controller on one of them.
My question is, can you use the battery without bypassing the BMS?
you can just put 42 volts on the charge port and the battery will charge. the bms does its work.

Hi SJAAK, I would be very thankful for a photo of your set-up. In particular how you solved the accelerator issue and a short description of the color-coding of the cables of the scooter which you found out while assembling it all. Unfortunately, I donÄt have a multimeter. Knowing which cable is what would help me match them with a new controller.

better buy yourself a multimeter first.
the accelerator has 3 wires, but bundled together with the brake wires. just try some combinations until the wheel spins.
